Embodiment 1

[0232] A microchannel reactor comprising an acrylic process microchannel with a rectangular cross-section and internal dimensions of 0.040 x 1.25 x 3 inches (1.02 x 31.75 x 76.2 mm) was fabricated. There is an apertured region in one sidewall of the process microchannel. The apertured region has a nominal pore or pore diameter size of 0.1 microns and dimensions of 0.010 x 1 x 1.5 inches (0.254 x 25.4 x 38.1 mm). The perforated area was constructed of stainless steel 316L and was supplied by Mott Company of Farmington, CT under catalog number 1110-12-12-018-01-A. The perforated area is connected with a gas distribution gas filling system and pipelines to allow gas to flow through the perforated area into the process microchannel. Palladium black and the catalyst in the form of nano-sized particles were dispersed on the inner walls of the process microchannels using carbon black as a dispersion / binder. The process microchannels are connected with tubing to allow liquid to flow...

Abstract

The disclosed invention relates to a process for conducting a multiphase reaction in a microchannel. The process comprises: forming a multiphase reaction mixture comprising a first reactant (214) and a second reactant (242); the first reactant (214) comprising at least one liquid; the second reactant (242) comprising at least one gas, at least one liquid, or a combination of at least one gas and at least one liquid; the first reactant (214) forming a continuous phase in the multiphase reaction mixture; the second reactant (242) forming gas bubbles and / or liquid droplets dispersed in the continuous phase; and reacting the first reactant (214) with the second reactant (242) in a process microchannel (210) in the presence of at least one catalyst (215) to form at least one product (216).

Description

[0001] Pursuant to 35 U.S.C. §119(e), this application claims U.S. Provisional Patent Application No. 60 / 628,163, filed November 16, 2004, U.S. Provisional Patent Application No. 60 / 697,900, filed July 8, 2005, Priority to US Provisional Patent Application No. 60,727,126, filed October 13, 2005, and US Provisional Patent Application No. 60,731,596, filed October 27, 2005. The disclosures in these prior applications are hereby incorporated by reference in their entirety. technical field [0002] The invention relates to a method for carrying out heterogeneous reactions in microchannel reactors. Background technique [0003] Heterogeneous reaction methods play an important role in the chemical and pharmaceutical industries. Depending on the phases involved, these methods can be classified as gas-liquid reactions, gas-liquid-liquid reactions, gas-liquid-solid reactions, etc. Reactions can be catalytic or non-catalytic. Catalysts can be heterogeneous or homogeneous. However,...
